My CLM applications are crashing again and again after every 6-7 hours.Have to restart the jts services to make applications up and running

OK. The problem has been fixed. The possible root cause was high server load by multiple Tomcat processes running. Killing the old processes fixed the issue.

Hi Pratibha,

I found your PMR and the javacores
It looks like you have 3 java processes running each using about 5 gigs of memory.
That is cutting it tight since it looks like your system has 16 gigs total memory.

One thing that might help the hangs would be setting the XMS value in the server.startup file

I am a bit concerned about having all three applications set to use 4 gigs of memory each as we don't want you to run out of system memory.
A resolution might require a bit of trial and error to get it right (unless you want to add system memory)
I would consider setting the QM and RM applications to use less, maybe set them to 3 gigs each and leave CCM at 4 gigs. Provided that CCM is the application that is under the heaviest use.
You would want to keep an eye on general performance after making that change.

Setting the XMS value:
It should be set to the same value as the XMX setting.
server.startup  will be in the following location:
/opt/IBM/JazzTeamServer/server
Currently you have:
set JAVA_OPTS=%JAVA_OPTS% -Xmx4000M

You will want to add this line after that one:
set JAVA_OPTS=%JAVA_OPTS% -Xms4000M

i.e.
set JAVA_OPTS=%JAVA_OPTS% -Xmx4000M
set JAVA_OPTS=%JAVA_OPTS% -Xms4000M
It will require a restart (or you can just wait till you are forced to restart)

One other thing I noticed in the PMR is that you restarted the database at some point and had trouble with RTC afterwards. If you restart the database it is advisable to restart RTC as well because there are usually stale connections to the database that need to be cleaned up.
